ValhallaRoom by Valhalla DSP is my most favorite reverb. Its sound is just incredible; even after testing it against other reverbs quite frequently (yes, I do it once a year at least ... kind of some OCD ...). The controls are intuitive and the GUI is minimalistic as always with Valhalla plugins. The CPU consumption is low. There are even some algorithms included, which need even less CPU. While mentioning all this, especially when comparing to other products (just basically think of almost any reverb out there), it is even the most affordable reverb. Also it has no silly protection system with which you have to install third party stuff and also no dongle is needed. It's also interesting to mention that ValhallaRoom gets still updated and even gets some new algorithms from time to time. I just love this reverb.
Only thing that could get better is the preset system. It feels a bit clumsy sometimes, but you can work with it at least.
With ValhallaPlate Valhalla has created a very intuitive and fast to use plate reverb, which is friendly on the CPU and sounds incredible. The GUI is minimalistic as always from Valhalla, which I personally really like. There are helptexts in the bottom, which describe the knobs (by hovering over them) or the selected algorithm character (if mouse is not hovering on a knob). The preset system could be a bit more complex, though.
Fantastic sounding dub delay with a lovely GUI. Can do some great self-oscillation if you crank the feedback dial. My only problem is that the modulation gets very OTT very quickly - would appreciate more range.
The only delay plugin you need. It does it all. I especially love the Tape and Ghost modes. Highly CPU-efficient and a simple easy-to-use interface that gets you where you want quickly. One of my most used plugins and the price, like all Valhalla plugins, ROCKS! Bravo.
